Get items in array from index 2:3

Question

I have an array myArray=[1, 2, 3, 4, 5]. I need to get items from index 2:3.

In Python this would be:

my_array = [1, 2, 3, 4, 5]
print(my_array[2:3])

How can I accomplish this in javascript?

you can use .slice – Abdelrahman Hussien Aug 01 '20 at 19:39 — Abdelrahman Hussien, Aug 01 '20 at 19:39

You can use the .slice function:

let my_array = [1, 2, 3, 4, 5];
let arr = my_array.slice(2,3);
console.log(arr);

Use Array.slice(first_index, last_index). Note that the element at last_index is not returned, so add 1.

If you want to return [3, 4], use my_array.slice(2,4). Remember, of course, that array indices are zero-based ;)
